Default Router speeds for different bits and types of wood

This is my first post after the intro and I have a few questions relating to general routing.

1. I have a Porter Cable 75812 router mounted on a Triton table top. I had to make my own fence as I bought this table top used with no fence, etc.. I also have a PC 6902 router, which I am selling now (fixed and plunge bases). With the 75812 router, can I use 1/4" bits or should I use only 1/2" bits?

2. Since the 75812 is a variable speed router, is there any resource available to find out what speeds I should run different bits at and what wood should be routed at what speeds? Being in Canada, it is quite expensive to find exotic wood and I am generally limited to curved pine lumber. Home Depot here only sells cedar, pine, oak and maple, unlike the many other varieties that I have seen being sold even in small towns in Wisconsin, USA.

3. I have been trying to make jewelry boxes using the pine bought from Home Depot and it always ends up being crooked, due to the curved nature of the wood. What wood should I use to make these boxes?

4. My router table does not have that round insert thing that sits around the bit, and it is very difficult to change the bits on this router unless you turn it from under the table and then bring it up. Is there a cheaper solution to this?

5. What methods do people use to accurately measure and adjust bit height?

6. What clamping techniques are available for cutting small pieces of wood on a mitre saw (holding it down with bare hands too close to the blade is dangerous)?

Thank you in advance

1... DO NOT sell that 6902... trust us... you will regret it...
either shank.. ½'' shank as a 1st choice and ¼'' when you have to...
2... see post #2 for the speed/material question..
3... what wood???... anything you can get your hands on...
straighten your wood... see the jointer substitute PDF...
4... straight wrench for the shaft under the table...
offset wrench for the collet nut from the top of the table...
and for safety sake get yourself the inserts and a starter pin for the top...
5... see your welcome link...
6... tell us about your saw and what blade you are using...

no worries...
change the bearings for real ones before you have issues and don't you mean 75182...

FWIW..
since you are using pine, clean your bits often and save them from becoming poor performers and an early death,...

4. a lot of folks have built there own tables. I built mine out of cheap plywood, based on the Oak Park table - used a Kreg insert plate. I've got a Bosch 1617 router installed in mine and can adjust bit height from above, but I can also lift the router plate and router out together for height adjustment.

You can see me table here; http://www.routerforums.com/table-mo...ml#post1713906

but you can also go through that thread to see pictures of other tables that have been built.

6. See this link for clamping/holding small parts on the miter saw - this guy shows some very ingenious ways of holding small parts - the video is long and he rambles a bit but it's well worth watching - https://www.youtube.com/watch?time_c...&v=knotpj60bsk

Some folks call me Vince - other folks call me...........

If your router table is wood, then its really simple to install a KREG plate with extra rings.

There are better plates, but at much more money.

Of the woods you listed, Maple should be the best for boxes.

Measuring bit height.......
https://www.amazon.ca/Trend-GAUGE-1-...er+depth+gauge

If you are talking very small pieces of wood on a mitre saw I would use a hot melt glue gun and glue them to a piece of sacrificial wood. Then let the saw come down gently, allowing the blade to cut, rather than just pushing down hard and forcing the blade through the wood.

Listen to the router and you will be able to tell if it's going too fast or slow and look at how the wood is being cut, don't get to hung up on tying to get the correct speed. The router might tell you 10,000 RPM's but that's about as much use as your car telling you its going 3200 RPM's. It's all about the marketing it sounds good when your shopping for the router. For the boxes I would go with maple.Oak doesn't look that nice when stained. If your table doesn't have several size rings then you need to get or build a table that has them. Without being able to reduce the space around a smaller bit your are risking an accident, without being able to use a bit larger than the hole in the table you are limiting the router. It isn't normally necessary to measure the bit height just set it and see how it looks,. Depending on how high or low your bit is the profile will be different. Once you settle on what looks best keep a sample and mark on it what bit was used. As far as cutting small pieces on a miter saw, don't. If you absolutely need to then clamp them down using the fence and a block of wood.

Welcome, Munib!

There are a lot of hardwood lumber sources in Calgary. These are just a quick few that I located...
Hardwood Lumber | Formations
http://www.blackforestwood.com/
https://www.windsorplywood.com/
Hardwoods

Home Depot would be my last choice. Any lumberyard will carry Pine and other softwoods; it's the hardwoods that you really want to get your hands on. Maple, Birch, Alder, being just a few of the domestic (Canada) hardwoods readily available.
