Transfer Screws--Making and Using-Pics

[300UGUY]

I've used them, but 30+ year ago. I have a set of transfer punches, I have used those quite a bit.

Based on your final measurements, I would have put a metric tape up there and read 100mm and 105mm!
You just need to figure out if it was designed metric or sae.

I probably would have done that also if the bolt pattern was square. Seeing the one bolt "out of position" made me a big leary. The pattern sure looks simple enough now, however.

My suggestion is the one you began with. I have used the gasket material many times to make a gasket and you can get accurate location for holes using small ball peen hammer, using the ball head.

I've used some of the transfer methods mentioned above and they work well and especially efficient for making gaskets.
I'm hoping to go near size on size for extra stability when bolting the loader mounts to the tractor chassis so need the hold locations to be reasonably precise. Press fit dowel pins would be good but doesn't look to be enough "meat" for the dowel holes.

I've never heard of them before but it looks like they would definately work great for presice hole placement. Thanks for posting them

I’ve used pretty much all the methods listed here except the screws and none are very accurate. The screws look fast and accurate.

Those screws look like the best approach, but here's another. After the 1st hole is drilled use a laser pointer to the center of the second hole, then install the plate with the first bolt and mark where the laser point is, remove plate, drill and repeat. I've found this to be very successful, especially since it accommodates any accumulative errors.

I just drill a small center hole on the head of the bolt in the lathe then measure to the center holes. Have a tram gauge and I used this system to align frame members on a 65 mustang.

Trick showed to me by an old mechanic.

Place paper or cardboard over the item and use round balls from bearings and gently tap while positioned over the bolt hole.
Lacking steel balls you can even use the round side of a ball peen hammer.

LOL, I have 1/2 and 3/4 old ball bearing balls in my tool box just for that.
Makes for a great transfer method. I've cut many a gasket with that method.

Crude, but also works, is to smear grease on the surface to be copied and gently press a clean sheet of white paper onto the greasy surface.

I have made them when I was in a pinch or for odd threads but decent hardened ones are pretty cheap.
