Sunbeam Tiger Bottom Side Engine Installation Time Lapse
This is a 26 second time lapse of a Sunbeam Tiger engine installation through the bottom with the front crossmember removed. Total time was about 2 hours and that includes close to 30 minutes filing a new motor mount to get it to fit. Plenty of planning and preparation made it go very smoothly.

HOMEMADE 6" LOUVER PUNCH
มุมมอง 61K3 ปีที่แล้ว
I was having trouble finding 6" wide louvers so with a little help from other TH-cam videos I fabricated my own tool. It is limited by the space between the guide pins but I was figuring on welding the louver sections into the hood anyway. This allows you to do this with a simple hydraulic press and not an English wheel type of setup. I was pleasantly surprised by how cleanly it cuts. Let me kn...
Nice! Works well. I'm about to build a louver press myself, will use a couple of lathe high speed steel blanks as my cutting edges, regular old 1018 steel for the rest of the die pattern. Thanks for posting the video!
Thanks. That should certainly give long life but how to you plan to attach the lathe blank?
@@thebluecaddy2950 Not hard to attach at all. The back of the bottom die machined from 1018 to louver shape, the cutting edge held in a machined groove with 3/8 set screws and a tack weld on either end. The punch is machined again from 1018 and the cutting edge area machined out to the size of the square profile of the bar of HSS and welded in with MIG in short bursts so you can let it cool between spots. HHS welded to 1018 actually makes a pretty strong union. I have a glass pack coring machine I built 25 years ago that punches 6 louvers around the radius of a length of exhaust tube. I would surmise each of the sIx HHS blanks has punched 3 million louvers without sharpening having just done the math.
Excellent results. Love the registration aspect. Now I have to work out how to do that on a large panel.
Thanks but I can't take any credit for the registration aspect. I just copied what I'd seen on other videos here.
Make the guide post farther apart. And you are really in business. Typical panel would be 24" apart.
Very good result. It also encourages me to make one. 👍👍👍
Go for it!
Thanks
Thanks
Would you be willing to sell them?
I wasn't really planning to but will consider it. How many louvres (punches) do you need and what gauge steel?
Excellent>>>>
Thank you!
How did you end up designing your die shape?
The louvres are 5/16" high so I did a full radius running all around the back side. For the back corners - when looking down on them - I basically copied what I'd seen on others. I rounded it off until it looked right. I think there is a standard look to them and I just tried to achieve that. They are 3/4" front to back and spaced 1 1/4" apart. That is pretty standard and does look traditional.
they look brill
Wow, exactly what i was looking for. Thanks.
You will love an air over hydraulic jack on that press. I put a HF 30 ton one on mine and will never go back to the old way. I finess the press with the pump handle, but the big steps are so much easier to just press the air valve and let it run down. I have a 90 deg bender like that and even built a round edge bender for making "J" hooks. Only I used old motorcycle fork springs to raise my dies back up.
hi, do you have a video of building process and dimensions. epic build
Thanks! No video of the build. I can say from researching the fab process of these punches, the most critical thing is getting the shearing edges positioned accurately and very close to each other - .005" or less. This ensures that they will punch the Louvre when pressure is applied and there will be no binding. Basic building sequence was first build the basic parts with the dowel pins. Next, mount the female half of the cutting tool on the base. Then temporarily mount the male cutting edge inside the female and onto the base with machine screws. (You can see the holes in the video) I did it with a .003" shim between the two cutting edges. Then I slid the top section over the big dowels and drill two 1/8 ' holes for dowels through the male cutting edge. Take everything apart, unscrew the male cutting edge from the base and now attach it to the top section using the 1/8" dowel holes to accurately locate it. All other dimensions are not critical, I just used material I thought was strong enough. Top and bottom sections are 1" x 2" 6061 aluminum I got from McMaster Carr.
Arriba peruuu carajoooo vean mis videos. De curveadoras rollss plisss yes ok
Good job 👍 You can add 2 spring on top of the die and connected to jack !
Geat video Thank you. You might want to try using leaf springs for your dies. They cut very well and last a long time.
1.6 mm thickness hydraulic pressing Ton capacity ?
I used a 12 ton press. I don't think this method would work with much less than that.
بسیار عالی خیلی قالب خوبی شده
Beautiful,thanks to posting it.Congratulations 👏👏👏👏👏👏👍
Hidraulic press ton necesseri?
The press in the video is 12 tons. It takes most of that to punch the metal.
Those are SHARP! And very well defined! Nice work! 😁👍
Thanks, I appreciate that. Honestly, I wasn't expecting them to come out as nicely as they did.
@@thebluecaddy2950 that's always a bonus! 🤣😂🤣 I love it when a plan comes together better than you expected!?
nice
Встанови пружини по боках пуансона , вони будуть самі розділять . хороша робота
Great job. Another way to make the punch and die, is to use regular mild steel, but to hard face the edges with commonly available hard-facing rods which are the equivalent of tool steel. :)
nice, to make more efficient of a process, you should extend the center circle to be a pipe that you can put a pin in to connect it to the rod of the press.
Thanks. That would work but I wasn't planning to punch a great number of them.
This is AWESOME Ian!!! The finished product is EXACTLY what I've been searching for, as I build my first car project. Your dimensions are just what I have sketched out! Please let me know if you would sell me a couple panels with 11, 6" louvers in mild steel plate (I've been working with 18 gauge but 14-16 would work as well) . I plan to weld or bolt them to my car. My email address is cjgaller@gmail.com and my youtube channel is Carl Galler Builds.
NICE!!!!
Thank you!
Nicely done, very neat and well formed louvre. 😉👍
Thank you. I actually arrived at these results faster than I thought I was going to. As I mentioned in the video, I learned a lot from watching similar videos here. I adjusted to the 6" louver I wanted. One tip I got and implemented was that it was critical that the cutting edges have only about .001" - .002 clearance between each other so I designed the tool to allow myself to be able to align them that accurately.
