- Homemade Bow Press - Part 7
In part seven I weld...
First you'll see I marked all the weld locations. This Just makes removing the galvanised coating (or weld prep) more efficient and allows you to remove only what you need to.
The receiving tube/main body has a weld seam that wouldn't allow the arm/jaw to slide freely so rather than removing the weld seam I decided to run a shallow cut along the arm to accommodate this seam.
I then clean all parts with acetone ready for welding.
I welded the press finger tabs/brackets on using the TIG as this would give me a narrow and more desirable weld bead for the fingers to swivel past.
I tack it all together using the TIG and finish weld using the MIG. Originally the plan was to only use the GTAW process but decided to save some time.

I love the 3 finger helping hand. Many times i've started to weld something and had it move. That would be really handy.
They are VERY handy. Pretty sure I took inspiration from Jody Collier ("weldingtipsandtricks" on youtube).
Appreciate your comment.
I wanted to thank you for the video. I used a couple of things from your videos when building mine. The lead screw nut cage to allow play and channeling the tube to compensate for the weld seam. Thanks again
Thank you Scott, I really appreciate your comment.
Very skilled, made it look like a work of art.
Thank you Braden, I really appreciate your comment.
Great build, although this is not your regular DIY :-) impressive. Nice project for next winter. I will need to simplify some aspects as I do not have the tools nor the skills but thank you for the inspiration.
Thanks Rob.
I apologies for the very delayed reply.
If I was to make another I wouldn't machine any of the parts. I'd just buy the correct size bearings to match the threaded rod. Another option is to use a trailer jockey wheel. They have most of parts you need, acme rod, thrust bearing, handle, etc etc.
Good Luck on your build and I appreciate your comment!
I was really hoping to see how the threaded rod was installed. The nut in the cage goes on the make end of the press. But how does the end with handle stay put on the end with the handle?
Sorry I should have shown the assembly process. There is a plate on the end of the main frame with a hole in it. The outer thrust bearing and handle portion of the rod are fed through this hole. Then the assembly is held together by the M10 nut on the end of the handle, i.e. it's purpose is as a capture nut that holds the assembly together when not under tension. Once the press is under tension the force is applied to the large inner thrust bearing. Hope this makes sense.
Nice Bow Press. Did you use 3/32 thickness square tubing? I was not sure if it would press 70lb bow!
Thank you. From memory it was made from 1.6mm(1/16"), But I will have to check, it's been a while, haha.
Compresses 70lb no problem at all, quite effortlessly actually.
How come you mig welded the final square tubing instead of tig?
Mainly to save time.
Appreciate your comment!
What subject did you make your bow press? Aluminum, iron or steel?
Hi Wilson, Frame is made from steel. Fingers are made from Aluminium(Aluminum).
Hi, how many to make me one? $$ look like it is bild like a tank.
Hi Zack,
Sorry I don't sell these, this was a one-off build.
I appreciate your comment.
