Undercutting door frames?

[Greg.B]

What you do for this is to lock it in and then wack it over and under the door frame. I had to do that many times when installing a laminate in my basement.

Am undercutting on the flooring job now, am using My Ryobi 18V recrip, and a 1/2" chisel. Of course I only had to do 3. Bill

MINE! .. the more money I can save on BS house renovations, the more money I can put into the shop

besides, I think you'd be surprised at how little 'sweat' it takes to operate a $10 HF saw for this job .... I'm all for power tools (read my sig ) but some things just don't require the inconvenience of a cord OR the $100 outlay

OK, what does that one and only purchaser of the BT3C Official Thong have to do with being for power tools??!!

I have the Fein and love it. It is VERY versatile. Having said that, it has one drawback - replacement blades are too expensive. It does not take too many projects to make the blade replacement cost more than then whole kit when new. While the Fein is a high quality tool, the company operates on the same principle of cheap printer companies - sell the printer but intentionally make more money on the ink than the printer.

If I were doing some contract work, I would not have a problem as I would include the cost of consumables in the bid.

I like the looks of the Bosch saw above, but it does not have the versatility of the Fein.

For more than a couple of doors, I would go with the Bosch.

Let me preface this that I love using a Japenese style pull saw. However, I bought the Bosch as a refurb for around $50 bucks and wouldn't do it any other way. I used a scrap of flooring with underlayment padding glued to it for a guide. I did all of the door jams in my house in 15-20 minutes.

Irwin makes a flush cut saw similar to the one at Rockler for $13.95. I have one I got at HD and it only takes a couple of minutes per doorway.

I rented a jamb saw from the local tool rental store for around $35 and I would do it again. Six doors in about 10 minutes. Done.

Another option is to buy a used saw on eBay or CL and resell after the project for about what you paid for it. On a new one, you'd have to factor in the significant depreciation, but on a used one that's already been done.

A little late backing Thom up on his suggestion, but I absolutely agree that the flush trim saw worked like a champ. Of course if I recall correctly, he did all the flush trim! LOL! Seriously, it worked fine.

Having said that, like another poster mentions I used a biscuit jointer to flush trim the majority of door jambs on this project. If you think about it a biscuit jointer is bascially a vertical circular saw like the jamb saw. I would have likely used it to finish off the jambs had my Dad not "borrowed" mine and took it to NC with him. The biscuit jointer plows through finishing nails, as evidenced by the sparks shooting out. If you want to power tool option this would leave you with a tool you would be more likely to use in the future than the Bosch trim saw. At $50 - $75 the Bosch does sound like a good tool. Other applications for the Bosch would be doing fine miter trims for picture frames.

You have a lot of input and a lot of great options.
